Letters Patent No. 86,044, 'dated Janna/ry 19, 1869.

To all whom it 'ma/y concern.-

Be it known that we, L. A. TRIPP and S. M. BOYD, of New York, in the county of New York, and State .of New York, have invented a new and useful Improvement in Window-Shade Fixtures; and we do hereby declare Vthat Vthe following is a full, clear, and cXact description thereof, which will enable others skilled in the art to make and use the same, reference being had t" the accompanying drawings, formingmpart of this specification, in which- Figure l is a front view of a window-shade to which our improvements have been attached.

Figure 2 is an end view of the same.

Figure 3 is a detail sectional view of the saine, taken through the line x, g. l, looking to the right.

Figure 4 is the same section as fig. 3, but looking to the left. v

Figure 5 is a detail perspective view of the detach` able cordguide.

Similar letters of reference indicate like parts.

Our invention has for its object to vfurnish simple, cheap, eiective, and vconvenient xtures for attachment to ordinary shade-rollers, which shall, at the 'same time, be so constructed and arranged as to allow the shade to be operated with the same facility as when 4a spring-roller is used.

It consists in the construct-ion and combination of the various parts of the fixtures, as hereinafter more fully described.

A represents the part of the window-casing to which the brackets B and C are attached.

The bracket B is formed with a round hole to receive the roller-pivot, which pivot is attached to a circular cap or plate, and is secured to the end ofthe roller D by nails or screws passing through the said plate and into the end of the said roller. i,

To the outer side of the pivot-plate is attached a sleeve, E, in which 'is placed a sliding bolt, F, which is prevented from dropping out of the outer end of the sleeve E by a stop-pin, or by closing up the said outer end of the said sleeve. As the roller revolves, the inner end of the catchbolt F rests and rides upon the catch-block G, which is securely attached to or formed upon the bracket B, and which has a shoulder formed upon it in about the position shown in fig. 4.

li' desired, the catch-block G may be omitted, and the inner end of the sliding bolt F allowed to rest and ride up0n.the pivot of the roller D. In -this case, a stop-pin', or equivalent projection, should be attachedto or formed upon the bracketB, in about the position of the shoulder of the catch-block G.

By this construction, when the shade is drawn up, or allowed to run down rapidly, the centrifugal force engendered by the rapid revolution of the roller D, throws and holds the sliding bolt F in the outer end ofthe sleeve E, so that it passes `freely over the catchblock G; but when the shade is allowed to move down slowly, the slidingr bolt F catches upon the shoulder of the catch-block G, and stops the shade, thus enabling the said shade to be adjusted to stand in any'desired position.

H is the spool, the inner flange of which is secured to ghe end of the roller D by nails or screws, as shown in g. 2.

lo enable the said screws or nails to be conveniently inserted, the outer flange of the spool H is cut away, so as to leave only wings, or a bar, h', upon each side of the shankV or body of the spool.

The outer end of the pivot attached to or formed upon the outer end of the spool H, projects through, gud works in a slot in the bracket O, as shown in I is the controlling-cord, the end of which is at tached to, and which is'wound around the shank or body of the spool H.

The lower endA of the cord I-passes through the guide-hole of the guide J, may, if desired, terminate in a tassel, and hangs in such a position as to be conveniently reached and operated. 4 v

The cord-guide J is made in about the form shown vin. g. 5, that is to say, it has a square projection formed upon the outer side of its upper end, which tits into ,the slot in the bracket C, and prevents the said guide from turning'. l

The guide J has a hole formed through its upper part, through which passes the pivot of the roller D,

so that the said guide may ride upon the said pivot..

The lower end of the guide J is bent inward at right angles, and has a hole formed through it for the passage of the cord I, as shown in the drawings. K is a button, attached to the cord I in such a position that when the shade is allowed to run down, the said button may strike against the guide J, before the shade has been wholly unwound from the roller D, so as to stop the revolution of the roller, and prevent the shade from being torn away from the said roller, as it would be liable to be it allowed 'to run entirely down. By this construction, the shade is raised or wound upon the roller D, and its movement controlled, when descending, by means of the cord I; but it descends, or is unwound from said roller, by its own weight, or by the weight of itself and of the tassel or tassels attached to it.

This construction enables lthe `shade and all its xtures to be detached by simply removing its pivots from the brackets B and C, without its being neces- ,sary to remove any cord or take out any screws;

Having thus described our invention,

We claim as new, and desire to secure by Letters Patent- 1. The sleeve E, constructed as described, upon the pivot-plate of the roller, and provided with the 'sliding boli', F, which is adapted' 'bo-move circumferentially around the shouldered stop-tube formed upon the .bracket B, as herein described, for the purpose specisage of the cord I, as herein described, for Jche purpose specied. y 4

3. In combination vwith the roller D, the sleeve E,

slidingpin F, bracket B, tubular shouldered. bearing- Gr, spool H h', bracket C, angular cord-gude J, and weighted cord I, as herein described, for the purpose specified.

The above specification of our invention signed by us, this 10th day of June, 1868-.
